Nandos Pinecrest. Rogues

Yesterday 18/08/ 2019, I purchased a meal totalling R233 at the Nandos in Pinecrest Center, Pine town better known as Sanlam Center. I paid by card and the cashier used a machine that declined the transaction, he then tried it again on the same machine and it declined for the second time. He then used a mobile machine and it went through, I received the SMS showing the deduction from the account. A few minutes later I received another SMS showing another deduction from the account for the same. I informed the cashier and manager who said to me that usually happens and while we eat it will be reversed but she was adament it would reverse and said on her system it only shows one decline. I was very upset and made a noise with then, then spoke to Raveen who is the area manager and a completely unhelpful person. He kept saying it is unfortunate, these things happen, its not their fault and I need to go to my bank and get a bank statement showing they have taken the money twice then they will look into it and reverse it. This is the response from Raveen and the manageress at Nandos, so besides them being aware of these things they continue to use faulty machines and ***** peoples money and then further inconvenience them with time spent going to the bank and then paying the bank for the statement so further cost to us and not to mention petrol costs or public transport costs to the customer and all they have to say is it is "Unfortunate". I also called the customer care line yesterday and was told they should have done the reversal at the store and they **** it would not reverse. I was assured of someone contacting me and given a ref. Number but its now been over 24 hours, my money has not come back into my account not has anyone from Nandos contacted me. As it stands I paid R466.00 for a R233 meal at Pinecrest Nandos yesterday. I will not , nor do I have the time to waste to run around and then lose further to the bank for the statement. Nandos Pinecrest are rogues as far as I'm concerned with this experience and it has cost me now R233 to hopefully save someone else the same situation coz their response will simply be " it is unfortunate". Nandos is a big franchise with millions of people purchasing there, how much money if added up are they *****ing in total this way from innocent customers.
